1 This invention relates to windows, and has reference more especially to supplemental windows with slidable auxiliary storm and/ or screen sashes adapted for use in connection with the permanent window of dwellings and other buildings.

My invention has for its chief aim the provision of a supplemental window of the kind referred to which lends itself to manufacture at relatively I small cost; which can be easily installed without entailing the use of any special tools other than an ordinary screw driver or the like; which is adjustable so that slight inaccuracies in the nominal dimensions of the frames of standard permanent windows can be compensated for and the need for fitting dispensed with; and from which the sashes can be readily and quickly removed from within doors when interchanges are to be made at different seasons of the year. I

How the foregoing and other advantages are realized in practice will appear from the following description of the attached drawings, wherein Fig. 1 is an outside elevation of a permanent window to which my improved supplemental window unit has been applied.

Fig. 2 is a broken-out vertical section of the organization on a much larger scale taken as indicated by the angled arrows 11-11 in Fig. 1.

Fig. 3 is a vertical detail section taken as indicated by the angled arrow III-II I in Fig. 1.

Figs. 4, 5 and 6 are fragmentary detail views in horizontal section taken as indicated respectively by the angled arrows IV-IV, VV and VI-VI in Fig. 1.

Fig. 7 is a fragmentary detail view looking as indicated by the angled arrows VII-VII in Figs. 3 and 6.

Fig. 8 is a perspective view showing one of the component elements of the supplemental window; and

Fig. 9 is a view corresponding to Fig. 2 showing a complete vertical section through the main and supplemental windows on a reduced scale and the manner in which the auxiliary sashes can be removed or placed from within-doors.

In these drawings the lintel, the sill and the lambs of the frame of the ordinary permanent wooden window are respectively designated by the numerals I0, H and I2, and the usual upper and lower sliding sashes by the numerals l3 and I4. After common practice the sill II is downwardly sloped for water shedding as at and provided with the customary stop shoulder at H. The supplemental window unit which I have devised for use with a permanent window such as above briefly described, includes a pair of auxil- 9 Claims. (01. 189-64) iary jamb members I! each consisting of two channel section rails l8 and I9 fashioned from sheet metal and dimensioned so as to fit one over the other in opposing relation as best shown in Fig. 4. The rail l8 has a projecting fin or flange 20 extending longitudinally of its back and constituted by a fold of the metal, said fin or flange being apertured at intervals of its length for passage of the shanks of beaded securing devices 2! which take into the shutter stop shoulder 22 on the corresponding jamb l2 of the permanent window frame. The rail I9 on the other hand is formed along its back with an outwardlyoffset box bead 23 for a purpose later on disclosed. Due to engagement of the rails is and I 9 in the manner described, the auxiliary jamb members I! can be adjusted for width, wherefore it is possible to adapt the unit to permanent windows which may vary slightly in their crosswise dimensions, the adjustments being fixable by clamp screws 25 of which the shanks threadedly engage in transverse registering slots 26 and 21 in the outer side faces of said parts.

The supplemental window unit of my invention further includes upper and lower auxiliary sashes 30 and 3|, those shown being' glazed and having frame bars formed from sheet metal. Except for differing somewhat in height, the sashes 39 and 3 l are generally similar in their construction. The frame bars 32 of the upper sash 30 are all of 2 cross section and welded or otherwise permanently secured at corners, with resultant provision of a rectangular perimetric recess for the glass pane 33 whereof the edges are bound with treated tape 35 of felt or the like for weather tightness, retainment being effected by sheathing strips 36 of spring metal which are formed with retroversions to snugly engage over the projecting flanges of the sash frame and which are engaged over and press against the felt strips at the outside of the sash. The sheathing strip 36a for the top bar of the sash 30 provides a retaining channel 31 for packing 3B which seals against an added wooden strip 39 on the lintel H] of the permanent window frame. The top and side bars 40 of the lower sash are likewise fashioned to Z section from stout sheet metal, but the bottom bar 4| thereof is of channelsection and formed with upwardly and downwardly projecting flanges. To the front of the bottom bar 4| of the lower sash is suitably secured a flat spring strip 42 of corresponding width with resultant provision not only of a perimetric recess for the pane 63 but also of a retaining groove for packing 45 along the bottom of said sash to seal against the top of a sill be again referred to.

Engaging with a. clamp fit over the box beads of the auxiliary jamb members i! are channel section sash guiding strips 50 of which one is separately illustrated in Fig. 8 said strips being of spring metal and jointly providing grooves SI and 52 for the sashes 30 and 3|, the outer walls 53 and 54 of said grooves and 52 respectively extending down and up approximately to a level midway of the height of the window. The projecting side edge flanges of the sashes and 3| are engaged in the groovesof the guide strips 60 in the manner instanced in Figs. 4 and 6. A weathering strip indicated at 55 in Fig. 2 insures against the entry of air or moisture through the interval between the bottom bar of the upper sash 30 and the top bar of the lower sash 3|. As shown, the weathering strip 55 is flxedly incorporated with the bottom bar of the upper sash 3|! and has a rounded sprin tongue 56 which frictionally engages the top bar of the lower sash 3| at the front or outer side. After being engaged within its guide grooves and raised to abut the lintel of the permanent window, the upper sash 30 is locked in position by means of slide bolts 61 confined in housings 58 on the bottom bar of said sash and engaged in suitably located apertures 59 in the inner faces of the box or parting beads of the supplemental jamb members 1, see Fig. 5. The lower sash 3| is similarly provided on its bottom bar with latch bolts 60 which are selectively engageable with apertures 6| at diiferent levels in the box or parting beads of the guide strips to hold said sash variously adJusted when ventilation is desired.

The sill adapter 46 is engaged at its ends in the grooves of the auxiliary jamb members I1 and is formed by two strip parts 62 and '63 of sheet metal which are secured together by screw bolts 64, the strip 62 being initially longer than the strip 63 and having its ends lapped about the ends of the strip 63 as shown at 65 in Fig. 6. From Fig. 3 it will be observed that the strip 62 is plain and flat, while the strip 63 has an inward flange 66 at the top which overreaches the top edge of the strip 62 and aifords a surface against which the packing at the bottom edge of the lower auxiliary sash 3| seals. Permanently attached to the outer face of the part 62 adjacent the bottom by welding or otherwise is a 2 section strip 61 which in conjunction with said part provides a retaining recess for weathering 68 which seals against the sill surface of the permanent window frame. By reason of being composed of the two separate parts 62 and 63, the height of the adapter 46 can be made to compensate for difierences or inaccuracies in the sill slopes of windows of the same nominal dimensions with assurance that the bars 32 and 40 of the auxiliary sashes 30 and 3| meet properly when said sashes are closed.- In any case the height of the adapter 46 will be such that its upper edge will be approximately even with the top 6 of the sill I. Preferably in practice, the part 62 is initially provided with holes for the shanks of the screw bolts 64, and after the proper position has been determined for it during the installation of the supplemental window, registering holes are punched into the part 63 for through-passage of the bolt shanks. Thus after the bolts 64 are once placed and the associated nuts drawn up, the parts 62 and 63 will be rigidly connected against the possibility of subsequent displacement in the desired permanent relationship.

In order to prevent the accumulation of rainwater behind the adapter 46 when auxiliary screen sashes (not shown) are substituted for the glazed auxiliary sashes 30 and 3|, I have provided devices IO, see Figs. 1, 3, 6 and 7, for raising it slightly from contact with the sill I of the permanent window. Each device 10 comprises an eccentric lift cam II which, upon being turned counter-clockwise from normal position about a screw stud 12 at the inner side of the adapter reacts with the sill after the manner shown in Fig. 7, each such lift cam having a flnger projection I3 for convenience of manipulating it. The stops shown at 14 and 15 in Figs. 6 and 7 cooperate with the finger projection 13 of the cam 1| in limiting the extent of rotation of the latter. The cams ii are in practice so proportioned that the lift imparted to the sill adapter is not in excess of the mesh gage of the screens. Thus insects are prevented from entering through the water-escape clearance beneath the adapter.

' Due to the provision of the sill adapter proportioned as just described, I am able to foreshorten the height of the lower auxiliary sash 3| so that it. as well as the upper auxiliary sash, can be removed from within-doors through the permanent window after the lower sash of the latter is raised. The procedure is as follows: The sash 3| is first elevated to the position shown in 'dot-and-dash lines in Fig. 9 until it is clear of the top ends of the walls 64 of its guide grooves, then dropped and swung inwardly as shown in full lines in Fig. 9, with its bottom edge amply clearing the top ii of the sill With the lower auxiliary sash 3| out of the way, the upper auxiliary sash 30 is released and dropped until it clears the bottom ends of the outer walls 53 of its guide grooves 5| whereupon it too can be angularly manoeuvred and finally withdrawn inwardly through the open main window in the same manner as the lower auxiliary sash.

Having thus described my invention, I claim:
